Nowadays, the Ethereum ecosystem fosters tens of thousands of different cryptocurrencies with different properties and use cases. They are designed to be used for paying for functions and are known as utility tokens. Some tokens, like Uniswap’s UNI token, are set to remain ERC-20 tokens; other cryptocurrencies, such as Binance Coin, have since jumped over to their own blockchains. Bitcoin miners charge transaction fees to process people’s transactions; a similar process applies on Ethereum. An incentive is created to encourage an Ethereum miner to process your transaction quickly. Transactions on a cryptocurrency network that transfer value off the blockchain.
A basic implementation of ERC-20 tokens
Atomicity in blockchain refers to all components of a transaction executing and completing as a whole; either the transaction goes through or doesn’t, and no component is completed in part. For those interested in understanding the token standards of other blockchain ecosystems, this University article has all the information. The above factors have led ERC-20 tokens to surge in popularity, paving the way for the initial coin offering (ICO) boom that began in 2017. With billions of dollars raised, a new generation of projects was launched during that time — with many becoming pillars of the cryptocurrency space. As of December 2020, there are 829 projects based on the ERC-20 token standard and over 350,000 token contracts, according to a dynamic list from Ethereum data provider, Etherscan. Like any cryptocurrency, ERC-20 tokens are not immune from security breaches.
- Consequently, this token standard empowers developers of all types to accurately predict how new tokens will function within the larger Ethereum system.
- Ethereum Request for Comments (ERCs) were changed to address standardization and documentation for Ethereum’s application layer.
- Called Ethereum Request for Comment (ERC) 20, the standard guides token creation so that tokens compatible with the Ethereum blockchain are interchangeable.
What is ERC20?
Given its role in transparency, accountability, and usability within the ERC-20 token ecosystem, the “balanceOf” function is indispensable. It grants users real-time visibility into token ownership, enabling informed decisions regarding token transfers, transactions, and interactions on the Ethereum blockchain. In the early days of Ethereum, developers faced challenges in standardizing token creation and interaction, leading to fragmentation and inefficiencies within the network.
It incentivizes users to share their bandwidth and resources, improving the network’s overall performance and speed.

Almost anything that can be owned, can also be tokenised – be it corporate shares, real estate, works of art, rights of use, vehicles…the list goes on.
Called Ethereum Request for Comment (ERC) 20, the standard guides token creation so that tokens compatible with the Ethereum blockchain are interchangeable. One such ecosystem and blockchain belongs to Binance, the cryptocurrency exchange. The team behind Binance created its own blockchain, the Binance Chain, from an Ethereum fork. Chainlink aims to connect the real world with blockchain through Decentralized Oracle Networks (DONs).
This helps to enforce proper permissions, ensure transaction legitimacy, and prevent unauthorized transactions. These functions provide a common structure for tokens so that they can be easily accessed, recognized, reviewed, and used. This reduces the confusion users and application developers would have if every smart contract’s token had different information contained within it. ERC-20 tokens should not be mistaken for ether (ETH), the native cryptocurrency of the Ethereum blockchain.
This compliance is also necessary for Ethereum to keep the promise of scalability; it ensures compatibility between the many different tokens created using the Ethereum ecosystem. The team behind SHIB created a decentralized exchange, Shibaswap, where users can trade and stake their tokens. There are thousands of ERC-20 tokens, and developers keep creating more regularly. Still, most of them likely aren’t of importance to the average investor or enthusiast. The ERC-20 standard defines six mandatory and three optional functions that each token must feature. As the Ethereum platform grew to become one of the biggest and most used blockchains in the world, so did the need for some sort of standardization.
To do so, tap ‘Buy’ from the Home Screen, then select the token to purchase and payment method. The Ethereum community, powered by the Ethereum Virtual Machine (EVM), continues to innovate with new tokens and newer standards such as ERC-1400 and ERC-998. Showing a commitment to adapt to the diverse and evolving needs of token users and creators.
Blockchain token standards are essential frameworks that help define how tokens operate on blockchains like Ethereum. These standards ensure that tokens can interact seamlessly with various applications and services within the ecosystem. In this guide, we will explore some of the most popular token standards, including ERC-20, ERC-721, and ERC-1155, and understand their significance in the world of digital assets. One big challenge is getting developers and users to switch from established standards like ERC-20. This requires demonstrating clear advantages and providing good tools and documentation. Another issue is interoperability – making sure that tokens based on different standards can work together.
